8dpo what day would you test?

Question

Trying to be patient and wait to take a test but can’t decide what day to do it. 3 diff apps give me diff expected period dates despite having the same info: 1 says Wednesday, another says Thursday and glow says Friday. 
Debating calling it even and testing Saturday but not sure I can wait that long. 
Anyone else the same dpo with me? If so, when are you testing?

Answer

12DPO

Answer

The chance of a negative is higher if you test before 12 DPO

Answer

I'm 7DPO! I'll probably test Tuesday (10dpo)
